Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sandbag making machine used to make waterproof sandbags during flood disasters or earth retention sandbags in earthworks.

[Prior art]

When flood damage occurs, a large amount of waterproof sandbags may be urgently required, and a large amount of earth retention sandbags may also be required during civil engineering work.

Traditionally, when making sandbags, workers use shovels to scoop up dirt and fill sandbags.

[Problem that the invention seeks to solve]

As mentioned above, when workers make sandbags by scooping up soil with a shovel and packing it into bags,
The work efficiency is poor and it is not possible to make a large amount of sandbags in a short period of time. Furthermore, in the event of a flood that requires the construction of a large amount of sandbags in a short period of time, the only option is to mobilize a large number of workers, but there is a limit to how many workers can be mobilized, so there is a problem that it is impossible to respond.

[Purpose and structure of the invention]

The object of the present invention is to provide a sandbag making machine that can advantageously solve the above-mentioned problems.

Two helical vanes 20 are fixed to the outer periphery of the hollow cutter shaft 19 by welding, and the tip edges of each helical vane 20 are arranged at an interval of 180° at the tip of the cutter shaft 19. A cutting blade 21 is attached to the tip edge, and the helical cutter 2 is constituted by the cutter shaft 19 and each helical vane 20 with the cutting blade 21 fixed thereto.

The helical cutter 2 configured in this manner is arranged so as to be inclined diagonally downward from the rear to the front, and has a rotating shaft 22 connected to the output shaft of the planetary gear reducer 18 in the cutter rotation drive device 1. is supported by a bearing box 6 through a bearing 23 so as to be rotatable and not move in the longitudinal direction of the shaft, and the bearing box 6 is fixed to a casing of a planetary gear type reducer 18, and the height of the cutter shaft 19 is A bearing box 6 is inserted on the level side, and a cutter shaft 19 is fitted to the tip of the rotary shaft 22 and fixed with a key.

The helical cutter 2 is disposed within an inclined guide member 3 having a U-shaped cross section that is inclined at the same angle and in the same direction as the helical cutter 2, and the higher level side end of the inclined guide member 3 is fixed to the support frame 8. At the same time, the tip of the helical cutter 2, that is, the end on the low level side protrudes from the tip of the inclined guide member 3, and an excavated soil discharge hole 4 is provided at the lower part of the high level side of the inclined guide member 3. One diametrical end of a bag opening attachment annular body 5 surrounding the lower part of the excavated soil discharge hole 4 is pivoted to the inclined guide member 3 by a horizontal shaft 25, and the other diametrical end of the annular body 5 is The end portion is suspended and supported by the inclined guide member 3 via a weight detector 26, and when this weight detector 26 detects a predetermined weight, a timer circuit is activated by a signal from the weight detector 26, and the cutter is suspended. The operation of the rotation drive device 1 and the expansion/contraction operation of the swing hydraulic cylinder 16 are stopped, and the buzzer sounds.

The self-propelled vehicle 7 is attached to the body 24 of the self-propelled vehicle 7.
A gear pump 27 driven by an engine is mounted, and pressure fluid is supplied from the gear pump 27 to the elevation hydraulic cylinders 11 and 14, the swing hydraulic cylinder 16, and the hydraulic motor 17 via a control valve.

FIG. 6 shows the sandbag bag 28,
A binding string 30 is inserted along the mouth edge of the bag body 29 in a zigzag pattern alternately on the front and back sides.

Next, the operation when constructing sandbags using the sandbag constructing machine of the embodiment described above will be explained.

The work is done in teams of two, one of whom is
This is a person who rides on the self-propelled vehicle 7 and operates the self-propelled vehicle 7 and the control valve of the sandbag making machine, and another person is responsible for attaching and detaching the sandbag bag to the annular body 5 for attaching the bag opening. In addition, he is the person who performs the work of binding the binding string 30.

When creating sandbags, first prepare the sandbag bag 28.
The opening of the bag body 29 is fitted into the outside of the bag opening attachment annular body 5, and the helical cutter 2 is rotated by the cutter rotation drive device 1, while the opening of the bag body 29 is fitted into the outside of the bag opening attachment annular body 5, and the helical cutter 2 is rotated by the cutter rotation drive device 1. The hydraulic cylinders 11 and 14 for elevation are operated to cut the tip (front end) of the helical cutter 2 into the ground 31 to an appropriate depth, and then the hydraulic cylinder 16 for swing is operated to reduce the helical cutter 2 and the slope. Earth and sand are excavated while rotating the guide member 3 over the range shown by the two-dot chain line in FIG.

The excavated soil is transported diagonally upward along the bottom of the inclined guide member 3 by the helical vane 20 of the helical cutter 2, and then passes through the excavated soil discharge hole 4 and the annular body 5 for attaching the bag opening. It is put into the bag body 29.

After turning excavation of a predetermined width, the self-propelled vehicle 7 is driven an appropriate distance to make a cut, and then the helical cutter 2 is turned again to start digging. When the bag body 29 is filled with a predetermined weight of earth and sand, a signal from the weight detector 26 causes a buzzer to sound, and the rotation and turning of the helical cutter 2 is stopped for a certain period of time. Remove the bag body 29 from the bag opening attachment annular body 5 and tighten the bag body 29 with the binding string 30.
The opening of the empty bag 29 is closed and tied, and then the opening of the empty bag 29 is attached to the annular body 5.

After the predetermined time has passed, the helical cutter 2
rotation and swivel will be started automatically.

Note that excavation may be performed while the helical cutter 2 is moved forward by the self-propelled vehicle 7 without turning the helical cutter 2.

When transporting the sandbag making machine, the helical cutter 2 and the inclined guide member 3 are raised and rotated to the position shown by the two-dot chain line in FIG. By the shortening operation 11, the support arm 9 and the part supported by it are rotated upward, so that the helical cutter 2 and the inclined guide member 3 do not collide with the protrusion of the ground.

〔Effect of the invention〕

According to this invention, the earth and sand excavated by the helical cutter 2 rotated by the cutter rotation drive device 1 is moved diagonally upward along the bottom of the inclined guide member 3 by the helical vane 20 of the helical cutter 2. The sandbags can be automatically filled into the sandbag bag 28 attached to the bag opening attachment annular body 5. Therefore, with a small number of workers, a large amount of sandbags can be filled with high efficiency using mechanical power. The sandbag making machine can be easily and quickly moved to any location by the self-propelled vehicle 7, and the helical cutter 2 can be easily cut by the self-propelled vehicle 7 at the excavation site. It is possible to achieve effects such as being able to move the object.
